19,363 pupils who achieved five or more A* to C GCSE grades including English and mathematics in 2007 at the end of key stage 4, had not previously attained level 4 or above in either English or mathematics or science at key stage 2. This was 6 per cent. of all pupils who achieved five or more A* to C GCSE grades including English and mathematics in 2007; including pupils in the independent sector.
Of these 19,363 pupils, only 621 pupils had valid data for their prior attainment at key stage 2. This represents 0-2 per cent. of those pupils achieving five or more grades A*-C including English and mathematics.
Missing prior attainment may be due to a pupil attending an independent school where national curriculum testing at the end of key stage 2 is not compulsory. There will also be no key stage 2 result for any pupils that were not resident in England when they were aged 11. Disapplied pupils and those pupils who were absent from school when the tests took place have been included in the figures.
